- allwhom it mag/ concern:

Be it `known thatI, PAULDAIMLER., a sub# ject ofthe King of Wrtemberg, and resident 'of Untertrkheim, Kingdom of Wi'irteinberg,

5 Germany,I have v'invented a new and useful Lubricator, of which the following i's-an exact specification.

This invention relates to lubricators in which a pump or pumps are employed-to deliver-oil'to a number o f'pl'aees .on an' engine or machine.

The improved lubrioatoris illustrated inA v"the accompanying drawings in which F igure' 1 is across section, Figi? 'is a longi- 1-5 tudinal section through the lubricat-or7 Fig. 3

is an outsideview of the lubricati'ir7 Fig. 4 is an outside 4view of the valve which I einploy, Fig. 5" isa development of the part of .the valve showing the shape ot' the-grooves Tlievshaft a is supportedV in a casing e in `the bottom part of which the oil .for circulation is placed. The pumps are in the form sliowncast in one with the cover of the casing e andthere is cast together with a cover a cylindrical body g from which tubes h, hL h3 lead. The passage Z leads from the cylindrical valve easing g' to the iunip. e vl-v in der d. `Within the pump cylinder d there works a piston eeoiinected b v rods b Fig. 2.

3 5 tecra-nk disks b on the shaft (l. (ln ashaft a there is also mounted a gear wheel g gearing with a larger gear wheel c which is tixedto the rotating valve ilwhieh is coinnioii vto all the pumpsA and which is shown sepaiatel 'in As seen in Figs.

sists of two conical parts oppositely' arranged withzjtheir narrow ends towards one-another and pressed against the eoiiieal Asurfaces .of

the valve c-sings q by means of a spring le gripping in cross pieces /r .at the end of both .the p arts t.

-As seen 1n Fig. 4 'the left'hand'part i is pro-il .vided with a lug 'n engagingin a rer-ess formed' 5o -on a proJection m on the right hand parte;

In this Way bot-h thepa-rts rotate together when one of them is moved by vmeans vot' the.

wheel-o. lo the cylindrical easing-y there iare also connected pip'esj one. lor ear-li ol' the. pumps d.' The pipesj. have been omitted iii Fig. 3 but this arrangementwill be under# stood from Fi.. 1. These ipes lead from the pertain t ie casing tojtIie lower end 'of the'oil containing space e. The valve parts i are provided with L-shaped grooves 'q p.

The circumferentially arranged parts p being in the same plane and, arranged v'opposite the .passage l'to the pump d andthe port r. The

axially arranged parts q extend on opposite sides of the circumferentially arranged grooves p. 1 i

The operation ofthe device as follows:

For each revolution of the valve i the shaft a makes two revolutions. The pump d during its suction stroke is vcontin'i'i'ally in communication with a 'part p vof thegroove which part is so' arranged that it establishes arcominunication between the po'rt r and the passage Z Durinv' the suction strokeof thepuinp the valve L makes quarterof'a revolution so as to close oit the port r by means ofthe stop i.

,At the saine time the stop i2 comes. opposite lthe opening leading' to the ipe outlets h2, hf'

and'h, so that oil is force in turn through thesel openings. It will be seen that during the motion ofthe groove part q over the outv lets h2, h and h; there are intervals-when the groove Aq will be entirely closed'. During these intervals the pressure of' the oil .iii the pump causes the valvepartfi to be pressed outwards and someof the oil finds its way be'- tween the valve 't andthe casing y.

'As seen. from Fig.- 2 there are :two `sets of pi es if, h', h", with which the opposite-ly avial y arranged grooves' q in t'urn'coperate -in the manner above described, so that each of' the pumps d may be arrangei'l 'to supply oilto 6 points-on the engine orma'chine and a very simple compact 'ai'ran'gement is ob-A tained in which 'there is no liability for the 'Amy invention, what I- desire to, se cure 4by Letters Patent-of` tlie'United States is:-v

1. A lubricator comprisingaplurality. of pumps, a common rotating distributing valve and ported casing for said pu'i'npsysaid valve having spring connected valve parts,

substantially as described.

'-2. A lubricatoil comprising al'pluralityofl pumps, a common rotating distributine' valve and ported casing for said pumps, sai( valve comprising; two oppositely arranged conical parts `.vit-li theirn'arrow ends-towards eaeh o1her, a slidable coupling between said ii'i an axial direction, 'substantially as de- )during the delivery stroke of the pump come I sueeessively and at intervals into commuscribed.

3, A lubrieator comprising in combination Witlia f un a valve casing having an inlet and afp; ra ity ofoutlets therein, a rotating valve in said easnig'liaviiig L-sliaped grooves therein the circuinferentially arranged parts of which coincide continually during the working strokes of tlie pump with the puin vinletand the axially arranged parts of -Wliio i nieitionj lwith outlets feircuinferentially disposedfaho'ut said valve.

eachl two revolutions rofy the pu-Inp .driving 5 plurality of pumps and a driving shaft therefor, a valve casing having oil suction and pump passages 'arranged in one plane in said 35/ casing, two groups'of outlet passages in said casing, said groups being arranged 1n planes on opposite sides of the plane containing the ypump passage, a rotating distributingvalve 11i said casing common to all the pumps and comprising "spring conneted ,conical arts, eac-li part being opposite a puinp an( provided With two L'sliaped grooves the circu'mferei'itial,parts of which grooves rotate in the plane of the pump passage, while t-he axial parts extend atdiametrically opposite points ofthe valve, one to each of the grou s of outletv passages,. a driving gearr from tie pump shaft to the valve, said/driving gear heilig arranged to rotate thevalve once for each tivo revolutions 'of"tlie, pump driving .iaft..
